Makes sense.
At the present time there are more total contributions than CPU.
In that state it is better to NOT go to extreme P+/-1.
If GPU resources diminish then I will lean to MORE P+/-1.

And unless P+1 takes into account how much P-1 has already been done it will be lower yet.
Or is prior P-1 not relevant to the success rate if P+1.

For my case do you have any recommendations for P+1 for choosing B1 based on how much P-1 has already been done?
